The "Auto Power On" Feature Seems Defective This set has a feature called "Auto Power On" that, according to the manual, "Turns TV On automatically when the cable box or a connected device is turned On". I have devices connected via s-video and the RGB component, but the TV will not turn itself on when any of these devices are turned on. My friend, who has the exact same model, confirmed that his won't turn on automatically either. I tried Panasonic tech support, but they were absolutely useless. The guy's end diagnosis was that maybe it only works for some devices. Basically, he had no idea and was just guessing. Doing a web search, I found that we're not the only two that has experienced this issue. I also found that there is a firmware update for the TV, but it doesn't say it fixes this issue. Can any other people out there verify if their set suffers from this same defect?

The intention of this feature is to enable the television to return to it's powered on state when electrical power to the television is lost and restored. If you are watching your television during a storm and their is intermittent power loss, when the power comes back, the television will turn on if it was turned on when the power is lost.Yes, this is how we can use our cable boxes to control the televisions. As it has been pointed out, it only works if your television is getting its AC power from the cable box (meaning there is an AC outlet on the box that you plug your TV). It's nothing more than that and not a feature specific to cable boxes.

I have the same problem and am have a call into tech support. They say they are testing and will get back to me. Any updates to this?

When I called tech support back in October, they described the functionality as I stated in my earlier post. I guess I got lucky and got a tech that knew what he was talking about.I am, however, getting a intermittent popping noise now from the rear of the TV... It has always been there, but it finally started bothering me enough. My local warranty service provider will take my TV set again this evening to attempt to fix the problem. Evidently there is a new kit for it.

A whole lotta good this function does considering most cable boxes or A/V receivers aren't capable of supporting a 50" plasma screen plugged into them. We're using a smart strip power strip to cut the TV's power when the receiver box is shut off. It's not my preferred solution but it's the best we could come up with.

I have a new Panasonic TH-46PZ800U which implements the same feature, and it wouldn't work for me either as described (I thought) in the manual. Apparently the A/C power of the TV must be plugged into something upstream that controls the power - some cable boxes have this feature. When the upstream device powers up it energizes the TV's A/C, which - instead of just sitting there plugged in - actually powers up as well. From the transcript of my chat with the Panasonic tech:Steve Hoge: What else besides the HDMI output of the Cable Box needs to be connected to the television in order to get Auto Power On to work?Myron: The power cord of the television is what need to be plugged in.So there you go.

I had this problem, too. But the manual should state "if the television's POWER is plugged into the back of the cable box." Alas, the TV is three-pronged and the cable box only has a two-prong outlet. I used the function on the cable remote to accomplish this, it's just a little slow to react.

Yes, they basically worded it incorrectly in the instruction manual. Enabling this feature will remember the On/Off state of the TV when it loses power. So if you unplug it while it is turned on, it will turn itself back on once you plug it back in. It has nothing to do with the video signal. I tried the tech support people and even they weren't aware of this.

To expand on what Marcus said, if you were to turn off your TV manually, the remote doesn't know that. However, if this happens, there's a Help button on the remote you can use to get everything working again. It asks you several yes/no questions about the status of your equipment, and once you're done going through that, then everything's working again.

Yes! We've been experiencing the same problem. The standby light flashes red and turns off by itself. We turn it back on and it shuts off again! Then we've also had the picture turn off but the sound is still on. We also bought it through Costco.

I believe you have to either touch the power button and turn it on or else simply plug it in and it starts on auto. I have been simply plugging it in and then unplugging it when its not needed.

It's hard to diagnose a problem with limited info provided. One thing you can always try is to re-boot your TV. Turn your TV off, unplug the power cord, wait for about 20 seconds and plug the power cord back in. Wait for another minute or so for your TV to re-boot and turn it on. Hope this will fix your problem.I've never experienced the kind of problem you described. I've had my 64-inch set for a little over a year now and the only problem I had was loss of 3D feature. My set did not recognize a 3D Blu-Ray and played it in 2D. After re-booting it using the method described above, it worked again. This happened only once. My TV has been working fine since.

same thing happens if you use the TV's USB power, it turns on when the TV does. Takes about a minute to boot up. Buyer beware though, these things suck, mine broke after 2 weeks

Hi Joseph, not sure if this will post under my account or not, but responding to the email: You know, I've tried...it seems like it will work at the same time for a minute...but then it stops. It's also kind of schitzo, and confusing to work. I push the right button and it doesn't go on, or I push both and they both come on, then I push the left and nothing happens, and it's unclear how to reset it. I compare it to how you push all the buttons on your remote when the TV is frozen. Seems kind of like that. Since my posting, I've stopped using it all together, because I thought that I'd just make the double light come on and flash, just for visibility. But then I discovered that it wouldn't last but for a moment. Oh well. I'm glad this was a gift, because I would have felt frustrated and returned it by now. :(

Not 100% sure. It could be a misbehaving signal source. I assume that your Input 1 is either plugged into your Cable/Set Top box or a Blu-Ray play. Try cycling the power by physically unplugging the power cord on whatever is plugged into Input 1. FYI, HDMI is an "Intelligent" interface so it tries to electronically identify the type of signal source plugged into each input. Sometimes it works, sometimes it doesn't. When it does, things work more intelligently. For instance, when I turn on my Samsung Blu-ray player which is plugged into Input 2 on my Mitsubishi, the TV turns on too without needing to hit the power button on the TV Remote. And sometimes, when I turn off the Blu-ray player, the TV will turn off too. Another possibility would be to try a new HDMI cable. The cable should be HDMI 1.3 or 1.4 compliant. If you don't have a new cable, but you have multiple cables, try swapping them and see if the problem moves with the cable.

I don't believe this unit will power back on by itself. I'm pretty sure you will have to turn it back on manually. I didn't find anything regarding auto turn on in the spec's.

If it's like mine, I start on HDMI when I power it up, it switches on its own to TV, then I have to press HDMI, so it sounds like a similar problem.

Unfortunately I just saw your post as I was looking for discussions regarding a problem that recently manifest on my 46VL150 from Costco. If in fact your 46V5100 is an identical model I suggest you return it ASAP! My problem is, as many have noted on their sets, the set turns itself off and the red standby light illuminates. No amount of turn off and on resolves the problem. Unplugging it for a protracted period gives you about 15- 20 minutes of "norma" play then the cycle repeats. Cannot comment on Sony repair yet since I am just now calling them. Good luck!

I'm having the same problem and it's intermitent. Sometimes it works and sometimes it doesn't. When it doesn't work, I have to turn the TV on and off several times and then it will work. Then sometimes the TV just turns on by itself. We have a Samsung technician coming tomorrow to check it out - hopefully I can post the solution...

We've been experiencing it off and on for about 6 months. Two nights ago, it was really bad...today...its not there. It comes and goes. In our case its a blue stripe. We've seen it whether its coming from the cable box or bluray player. I haven't played with it too much, so I don't have a pattern of what it does and how to defeat it. I'd like a comment from Panasonic. Our TV was 5 years old at Christmas.

Yes, and I had no idea this was a feature of this system until I accidentally turned on the Airplay on my computer before turning on the receiver. It does power on automatically. There is a slight delay before the stream kicks in.

The one I bought didn't work but I think it has more to do with my TV because I got sent a second on for free and I had the same issue of a black and white screen. I realized though that all I need was the S cable since both my computer and tv have connections for S cables and the screen with that connection the screen was in color. Check and see if all you need is an S-cable before you buy this product because if you buy an S cable it will be better quality than the one that comes with this set.

Out of the box it functions just like a normal monitor/tv would: no automatic on with power cycle. There might be a way to change it in the settings, but that wasn't in our customer specifications, so we didn't mess with it.

Mine did the same thing before it quit turning on completely. There's a part inside that is failing, and unless you are still under warranty it will cost more to fix it than it will to buy a new one. I ended up having to buy a new, different tv. I wish you luck but unfortunately you are probably going to need to purchase a new tv.
